| Outline of Final Research Achievements |
We developed a new mobile fronthaul system for transmission of large-scale multiple-input multiple-output radio signals in high frequency bands, using: (i) high spectral efficiency radio-over-fiber system; (ii) high-precision carrier signal generation, and (iii) high-output integrated photodetector.
|
| Academic Significance and Societal Importance of the Research Achievements |
The developed system is the first kind of seamless system in high frequency bands that can support large-scale MIMO signal transmission. It can reduce the system cost, complexity, and power consumption, and is promising for facilitating the deployment of new radio access networks in 5G and beyond.
